The Drawings:
Figure 1 is a side elevational view partly in section of a toothbrush in accordance with this invention;
Figure 2 is a front elevational view of the toothbrush shown in Figure 1; and Figure 3 is a side elevational view partly in section of the toothbrush shown in Figures 1-2 in a different phase of the operation.
2c Detailed Description:
The present invention is in general directed to an electric toothbrush with a head that orbits in a random man-ner so as to remove more plaque and debris with less effort.
By moving in such a path the toothbrush should be move effi-cient at removal of plaque and debris than a standard orbit head of an electric toothbrush.
Figures 1-3 illustrate a toothbrush 10 in accor-dance with this invention. As shown therein the toothbrush includes a hollow handle 12 and a head 14. Handle 12 would house the power drive for the toothbrush. This could include, for example, a motor 16 controlled by switch 18.
10 Actuation of the motor which is part of a drive structure causes later described drive transmitting members to effect a random orbital motion in the head 14. More particularly, head 14 has a front face 20 which includes a support member 22 rotationally mounted on a first shaft 24. As illustrated support member 22 is eccentrically mounted on shaft 24. A
carrier member 26 is mounted on a second shaft 28 to support member 22. Second shaft 28 is displaced from first shaft 24 by the distance "A". As a result, when support member 22 is rotated on its first shaft 24 carrier member 26 is driven in an orbital path. Front face 20 includes a recessed receiv-ing area 30 which defines the limits of that orbital path.
As best illustrated in Figures 1 and 3 support member 22 is mounted below the outer surface of face 20 in the recess 30. Carrier member 26, however, extends out-wardly from the outer surface of face 20. Carrier 26 is provided with cleaning elements 32 extending outwardly from the outer face of carrier member 26. Carrier member 26 is freely mounted on its second shaft 28. As a result, when carrier member 26 is driven in its orbital path carrier mem-ber 26 also freely or randomly rotates about its own shaft 28. In the illustrated embodiment carrier member 26 is axi-ally mounted on shaft 28. If desired, however, carrier mem-ber 26 could be eccentrically mounted so as to increase the random orbital path that carrier member 26 and its cleaning elements 32 take. In the preferred illustrated practice of this invention carrier member 26 is a disk having a circular outer surface from which the cleaning elements 32 extend.
During operation of toothbrush 10 the carrier mem-bers 26 and their cleaning elements 32 would move in the or-bital path which is transcribed by the outer wall of recess 30. Thus, Figures 1 and 2 show the carrier members 26 in one position located furthest from the handle 12. Figure 3 shows the carrier members moved to the opposite end of the path where the carrier members are closest to handle 12.
The invention could be practiced with a single carrier member and a single support member. As illustrated, however, a pair of such carrier members 26,26 and support members 22,22 is provided. The invention can also be prac-ticed where there are more than two sets of carrier members and support members.
The drawings illustrate the cleaning elements 32 in a schematic manner. Any suitable cleaning elements may be used such as bristles or elastomeric members including massage elements.
Any suitable drive structure can be utilized for creating the random orbital path. Such type of path, for example, is known from random-orbital sanders. Reference is made to U.S. Patent-No. 4,120,084.
The '084 patent describes a type of drive structure that could be adapted for creating the random orbital path of the, cleaning elements 32. Such structure, in general, includes a drive shaft 34 which would be driven by motor 16. Drive shaft 34 rotates in a longitudinal direction. A worm gear 36 is mounted at spaced locations on shaft 34 in accordance with the number of sets of carrier members and support mem-bers. Worm gear 36 drives gear 38 (see Figure 1) which in turn drives first shaft 24. Second shaft 28 is displaced from first shaft 24 by the distance A. As a result, during the driven rotation of support member 22, carrier member 26 moves in an orbital path. Second shaft 28 may be mounted in roller bearings 40 as described in the `084 patent.
Although reference has been made to U.S. Patent No. 4,102,084 for an exemplary type of drive mechanism other types of drive mechanisms may also be used such as known for random-orbit sanders. Reference is also made to U.S. Patent No. 4,854,085.
In general, a drive mechanism would be used wherein the drive structure includes a motor, preferably lo-cated in the handle.of the toothbrush. The motor actuates drive transmitting members which cause a first shaft to ro-tate. A support member which could be in the form of a disk or block is eccentrically mounted on the first shaft. A
second shaft is mounted to the outer surface of the support member. A carrier member which is preferably a disk is freely mounted on the second shaft. Thus, when the drive structure is actuated the support member is directly driven by the drive structure which creates an orbital path. Be-cause the carrier member is freely rotatably mounted on the support member the carrier member would rotate in a random fashion while being moved in the orbital path.
In accordance with some embodiments of this invention the head of a toothbrush includes at least one carrier member from which the cleaning elements extend outwardly. The carrier member is mounted to the front face of the head in such a manner that the carrier member and the cleaning elements move in a random orbital path.
In a preferred practice of some embodiments of the invention the carrier member is mounted to a support member. The support member is eccentrically mounted on a shaft so that when the support member rotates the carrier member moves in an orbital path. The carrier member itself is freely mounted for rotation with respect to the support member so that the carrier member rotates in a random fashion while it is moving through the orbital path.
According to one aspect of the invention, there is provided a random orbital toothbrush comprising a handle, a head secured to one end of said handle, said head having a front face, at least one carrier member having outwardly extending cleaning elements, and a drive structure mounting said carrier member to said front face for moving said carrier member and said cleaning elements in a random orbital path, wherein said at least one carrier member is a disk mounted to a support member, said support member being eccentrically mounted to a first shaft, said drive structure being engaged with said first shaft to rotate said first shaft, a second shaft mounted to said support member offset from said first shaft, and said disk being mounted to said second shaft.

As a result, when support member 22 is rotated on its first shaft 24 carrier member 26 is driven in an orbital path. Front face 20 includes a recessed receiv-ing area 30 which defines the limits of that orbital path.
As best illustrated in Figures 1 and 3 support member 22 is mounted below the outer surface of face 20 in the recess 30. Carrier member 26, however, extends out-wardly from the outer surface of face 20. Carrier 26 is provided with cleaning elements 32 extending outwardly from the outer face of carrier member 26.
